Does anyone know what I am talking about? I watched it a few times on TV as a kid in the 80's, it could have been a made-for-TV movie, don't know. It seems to me a young brother and sister had to spend a summer at some old house, don't know why, and the boy, I think, encounters the ghost of a little girl asking for help. All I remember for sure is the climax, where it is revealed the little girl had been thrown in a well along with her porcelain doll, and when it is found it gets broken, and diamonds are inside -- hence, the motive of the girl's murder.

I would love to know what this is called, so I can see it again. It reminds me of "The Changeling," which is one of my favorite movies. It is also in the vein of "The Lady in White.":confused:
